Just make the life boring stuff and irritancy, the people have the dream can be go along the road of dream, they will be very steadily an easy to be successed,and actually,the people do not have the dream are easier turn to the bad road,because they do not though about their own future,and very easier fall deep to the darkness life...

而且，他们也不会有什么远大的梦想，因为他们没有时常为以后的事做准备，同样的，也更谈不上梦想了，他们不会像有远虑的人一样朝着有梦的方向奔跑，他们只会吃一天，混一天，还会感觉度日如年，也许年轻时确实有前辈和父母喂他们撑着腰，但是他们但他们长大后，不会有任何奋斗的志气，也只是懂得吃喝玩乐拉睡，只会过那种无聊而且令人讨厌的生活，有梦的人会跟着梦想的轨道踏实地走动而不会坠入不正之路，无远虑之人就会很容易地跟着斜道走，很容易就会坠入黑暗的深渊而无法自拔。。。

The great tour purchasing power is the drive power of promoting the region's tourism developmentln the regional space, scale economic and regional separation are one of the basic characteristics of promoting tourism industry, So we must arrange the regional tourism industry with a systematic method and give prominence to the central city. For its outstanding area in the regional space, central city has evident superiority in the regional ecnomic development, and has echelon between central city and its periphery scennic spots, which is the inducement mechanism of tourism industry's arranging, developing and advancing step by step. For the law of diminishing marginal utility and the theory of equilibrium, the max utility equilibrium of tourism consumption be at the point of tangency of undiscrepancy curve and the cost budget curve.

中心城市居民巨大的出游力是拉动其周边旅游地发展重要的内在驱动力；由于地缘关系，区域规模经济与地域分割并存，是旅游产业运动的一个基本特征，为此必须对区域旅游经济进行系统化布局，突出中心城市的产业中心性；因其区位条件独特，中心城市在区域经济发展中居于明显的优势，与周边城乡部位存在经济发展上的梯次性，这种梯次性是区域旅游生产力布局、产业发展梯次传动，最终整体联动的经济诱导机制；根据边际效用递减规律和旅游者最大效用均衡理论，旅游消费效用最大化的均衡在无差异曲线与开支预算线的切点(即旅游目的地选择的最佳位置)上，且随着边际效用递减，目的地选择的最佳位置向远离中心城市方向移动，这就是中心城市与周边旅游地互动关系的经济学解释。

Currently, almost all the corrections of radar wave refraction error are based on the assumption that the atmosphere is homogeneous in the horizontal direction, and the azimuth error in the measurement of radar is not corrected.

目前进行的雷达电波折射误差修正，几乎都是建立在假设大气在水平方向均匀的条件下，认为雷达测量的方位角无折射误差，其对于下垫面均匀的平坦地区是可行的，但下垫面复杂地区方位角的折射误差必须修正。

After a flurry of ciaos, 4,000 misdirected passes and a good old fashioned handshake, my passing had improved from utterly hopeless to merely below average."It's all about technique and concentration," Pirlo explained. I spent years working at my game to get to where I am.

为了对比，有必要做一些自我介绍，我在12岁那年被学校足球队除名了，因为我在9场比赛中打进了4个球，可惜进球方向是朝着自己的球门，我最后一次踢出过顶传球击中了我奶奶的晾衣绳，然后飞进了邻居的温室，经过无数次被轰退场的激励、4000次无目的传球和一次次善意的老套握手，我的传球水平终于由不可救药提高到了比平均水平差一点点的程度。

In contrast, I was dropped from my school team at 12 for scoring four own goals in nine games and the last time I hit a lofted pass it deflected off my grandmother's washing line and broke my neighbour's greenhouse. After a flurry of ciaos, 4,000 misdirected passes and a good old fashioned handshake, my passing had improved from utterly hopeless to merely below average."It's all about technique and concentration," Pirlo explained.

If subjecting himself to his own observation, a man perceives that his will is always controlled by the same law (whether he observes the necessity of taking food, or of exercising his brain, or anything else), he cannot regard this never-varying direction of his will otherwise than as a limitation of it. If it were not free, it could not be limited.

假如人在观察自己的时候，他看出他的意志总是按同一法则活动（他观察吃饭的必要性或者头脑的活动，或者观察任何别的现象），他不能不把他的意志总是沿着同样的方向活动看作意志的限制，如无自由，则无限制可言。

As gloomy as China's pollution picture looks today, it is set to get significantly worse, because China has come to rely mainly on energy-intensive heavy industry and urbanization to fuel economic growth. In 2000, a team of economists and energy specialists at the Development Research Center, part of the State Council, set out to gauge how much energy China would need over the ensuing 20 years to achieve the leadership's goal of quadrupling the size of the economy.

中国的污染图景已然灰暗无光，然而它却将朝更糟的方向发展，因为中国已经到了主要依赖高能源消耗重工业和城市化助燃经济增长的阶段。2000年，一组国务院发展研究中心的经济学家和能源专家，开始计算今后20年为达到领导层的经济总量4倍增长目标所需的能源消耗。

The percentage of strong positive expression of MUC2 in SSDH group, slightly higher than it in SSW group , which may indicate a diminishing trend of the expression of MUC2,which might prompt the direction of the development of the disease ,and could provide a valuable signal on the disease prognosis and treatment.

脾胃湿热组、脾胃虚弱组MUC2表达无显著性差异，但脾胃湿热组MUC2的强阳性表达率较脾胃虚弱组略高，这可能说明脾胃湿热证和脾胃虚弱证之间粘蛋白的表达呈递减的趋势，即肠粘膜的防御保护功能下降，而这种递减可能提示了疾病发展的方向，可能对疾病的转归及临床治疗提供有价值的预示。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
